How reliable is the stock air filter gauge? I don't think mine has ever moved. How often does the filter need to be changed? I have heard that it is to hard to actually check the filter to see how dirty it is.

Before I installed a DIY Intake this weekend, I changed my filter every other oil change.....more often if in dusty conditions which I never was. When I bought the truck it has a drop in K&N which I took out the very next day and have been using Fram Tough Guards until this weekend. I never saw my filter guage move either.

Mine has never worked either, it never moves. Right before I ran out of warranty I had replace it. I still don't think it works. I just replace my filter every other oil change. Same for the fuel filters.

There you go Clippers. 2 out of 2 Superduty owners change their air filters every other oil change!

Mine hasn't moved Yet (Only 27K on it right now) I have read in more than a few places that the gauge will not move until the filter starts getting severly clogged,I need to find the link,but I have read the stock Donaldson filter can hold 3 Lbs of dirt!!

It's a 100.00 bucks or so at the dealer last time I checked,I don't have the manual handy,but I believe Ford says to change it every 30K,at 100.00 bucks a pop, I know I don't change it every other oil change LOL..
